QB_RB_WRITE_TO_FILE(3)

💾 QB_RB_WRITE_TO_FILE(3) 💾

okay bestie, so this is a page from the libqb Programmer's Manual, section 3 — yes, the 3 means it's a library function, we love a lil section number moment 💅

---

✨ NAME ✨

qb_rb_write_to_file — Write the contents of the Ring Buffer to file.

like… it literally does what it says on the tin, no cap 🫶

---

🌸 SYNOPSIS 🌸

#include <qb/qbrb.h>

ssize_t qb_rb_write_to_file(
    qb_ringbuffer_t   *rb,  /* ringbuffer instance */
    int32_t            fd   /* open file to write the ringbuffer data to. */
);

she's giving clean signature energy 😌✨

---

🎀 PARAMS 🎀

• rb — ringbuffer instance. your lil ring buffer babe, the whole point of the operation 💖
• fd — open file to write the ringbuffer data to. note the word open — like, already opened, bestie, this is a file descriptor not a filename, don't come at her with a path 🙈

---

🦋 DESCRIPTION 🦋

okay so. this section is lowkey empty in the original. like, genuinely nothing here. not me defending it, just keeping it 100 with you 🫶 the function name and the params are doing all the heavy lifting on this one.
